Very nice!! I don't know if you know there is an amazingly detailed free model of this ship available for free. It is scale-able to whatever spheres you can find. Link below for those of you who would like to make their own. It is very detailed.

I have to admit I like your model a lot. Your ability to make something from almost nothing amazes me. Your "Bubble Ship" looks like a "Hi-Performance" version of the Bubble ship. You are still "an effective team" says the "Mothership.
